There's been so great post on agent blogs lately about what exactly they want to see in their slush pile so it's time for some linkage (ahd here's fair warning that I may use a lot of linkage-type post for blog posts during Nano):
Weronika Janczuk's agent wish list
Mandy Hubbard Wishlist
Kathleen Ortiz Expanding what she's looking to sign
Every couple of months, Donald Maass lists on his agency's website what they are looking for. Click here for the link.
Enjoy the linkage!
